Intraday total column ozone measurements at Belsk, Poland, with the Dobson spectrophotometer no.84 since March 23, 1963 up to December 31, 2019

A homogenized long-term dataset comprises results of the total column ozone measurements with the Dobson spectrophotometer no.84 at Belsk (51.835079°N, 20.791437°E) in central Poland. The observations were made manually at intervals depending on weather conditions. The Station is managed by the Institute of Geophysics, Polish Academy of Sciences. The data series contains the results of all intraday Dobson spectrophotometer measurements since the beginning of the ozone observations at Belsk (March, 23, 1963) up to December 31, 2019 together with the corresponding ozone air mass, cloud type over the station, and the observation codes including used UV wavelength pairs and the observation type. The data set allows to study the ozone column variability over wide time scales, from intraday oscillations to decadal trends. This is important because the ozone layer protects the Earth from harmful UV rays. The ground-based data base could also be used to validate satellite observations of the atmospheric ozone.

本均一化长期数据集包含波兰中部别尔斯克（Belsk）地区（51.835079°N，20.791437°E）由第84号多布森分光光度计（Dobson spectrophotometer）获取的总柱臭氧测量结果。观测工作需根据天气状况人工间断开展。该观测站由波兰科学院地球物理研究所（Institute of Geophysics, Polish Academy of Sciences）运维管理。本数据序列涵盖自1963年3月23日别尔斯克臭氧观测启动至2019年12月31日期间所有日内多布森分光光度计测量结果，同时附带对应臭氧气团、观测站上空云型、以及包含所用紫外波长对与观测类型在内的观测编码信息。该数据集可用于研究从日内振荡到年代际趋势的多时间尺度臭氧柱变化特征。这一研究具有重要意义，因为臭氧层能够保护地球免受有害紫外线辐射。该地基数据库还可用于验证大气臭氧的卫星观测结果。
